SPECIFICATION forming part of Letters Patent No. 693,584, dated February 18, 1902. Application iiled June 9,1900. Serial No. 19,762. (No model.)

T @ZZ whom it may concern.'

Beit known that LWILLIAM T. M. BRUNNE- MER, a citizen of the United States, residing at Bradley, in the county of Kankakee and State 0fIllinois,have invented certain new and useful Improvements in Seeding- Machines, of which the following is a specication, reference being had to the accompanying drawings.

My invention relates to seeding-machines,

and has more particularly to do with checkrow corn-planters, although my invention includes the application of the improvements described to other machines.

My invention consists in improved mechanism for applying fertilizer to the soil at the time the seed is planted, and more specifically in operating the fertilizer-applying mechanism in conjunction with the seed-dropping devices.

It further consists in improved feeding mechanism operated by the usual check-row wire, said feeding devices being arranged to insure the proper feeding of the seed to the seed-tubes.

IVhat I regard as new will be set forth in the claims.

Referring to the drawings, Figure 1 is an end elevation, some of the parts being in section; and Figs. 2 and 3 are plan views, the seedboxes being removed, illustrating the seed-dropping devices in different positions.

In the drawings, 4. indicates the front or runner frame of a seeding-machine provided with the usual runners 5 or otherfurrowopening devices.

6 indicates one of the usual seed-tubes arranged to receive the seed from the seedbox 7 and deliver it to the furrow back of the furrow-opener 5. The seed-tube 6 is provided with a check-valve S, mounted on a pivot 9 and extending across the seed-tube, closing the passage thereof, as shown in Fig. 1. A spring 10 normally holds the valve S in closed position.

1l indicates a plunger arranged in the seedtube 6 and pivoted at its upper end to an arm 12, mounted upon a rock-shaft 13, which is supported in the frame t and extends transversely thereof in the usual way. The rockshaft 13 carries at its ends the usual forks 14, which engage the knots 15 of the check-row wire 16 in the usual way. By this construction as the rock-shaft 13 is rocked by the operation of the check-row wire the plunger 11 reciprocates in the seed-tube 6, its downward movement opening the valve 8 and discharging the seed in the tube on the ground.

The construction thus far described is not new and is not herein claimed.

16 17 indicate the usual guides for a checkrow wire.

1S indicates a fertilizer-box arranged in the frame 4 back of the seedbox 7, as shown in Fig. 1. Said fertilizer-box is provided with a fertilizer-tube 19, which extends therefrom down back of the seed-tube 6 and terminates near the ground, as shown. The fertilizertube 19 is provided With a valve 20, mounted on a pivot 21, as shown in Fig. 1. Said valve is normally held in position to close the passage in the tube 19 by a link 22, which connects said valve 20 above its pivot with the valve 8 below the pivot of the latter. The spring 10, which holds the valve 8 in position to close the seed-tube, also holds the valve 20 in position to close the fertilizer-tube 19. Vhen, however,.the valve 8 is rocked to open the seed-passage, the valve 2O is also rocked automatically to open the passage in the fertilizer-tube,the fertilizer being therefore applied to the soil with the seed. Suitable Valve mechanism is provided in the bottom of the fertilizer-box 18 for feeding the proper amount of fertilizer to the fertilizer-tube at suitable intervals. In the drawings I have illustrated such feeding mechanism as consistingof a disk valve 23, provided with a beveled gear 24, operating from a sprocket-wheel by a pinion 26, the sprocket-wheel being driven by a chain 27, in turn driven from the carrying-wheels of the machine, the latter not being shown. The fertilizer-feeding mechanism may, however, be operated by the check-row wire or may be of any other approved construction.

The specific mechanism for feeding fertilizer to the fertilizer-tube not being a part of my present invention is not illustrated in detail, and l wish it to be understood that any holes 29.

of the well-known feeding devices may be employed, my present invention, so faras the fertilizer-supplying mechanism is concerned, being limited to the operation of the fertilizersupplying devices in conjunction with the seed-feeding mechanism, so that the fertilizer is supplied to the seed as it is dropped, and, secondarily, to the automatic operation of such fertilizer-supplying mechanism by the opera-tion of the valve in the seed-tube.

The feeding devices for feeding the seed in the seedbox to the seed-tube are best shown in Figs. 2 and 3. As is illustrated therein, in the bottom of the seedbox is provided a seed-disk valve 28, which is adapted to rotate therein i'n a horizontal plane and is provided with a series of holes 29, through which the seedrpasses from the seedbox to the seed-tube 6. Each of said holes 29 is of the proper size to contain the number of seeds which -ittis desired to plant in each hill, and such number of seeds are fed to the seed-tube as each hole comes into alinement with the upper end of the seed-tube in the usual and well-known way. The seed-disk 28 is, rotated by means of a. pawl 30, pivoted by a pivot 31 to an arm 32, pivotally mounted on a suitable support 33. Said pawl 30 is provided with an arm 34, which is connected by a link 35 with an arm 36, secured to the rock-shaft 13, as shown in Fig. 2. The arm 34 is arranged opposite the pivot 31 and projects toward the fork 14, so that when the yrock-shaft 13v is rocked by the operation of the check-row Wire the link 35 pulls back on the arm 34 and throws the rear end of the pawl 30 inward toward the seeddisk 28. The pawl 30 is arranged slightly below the seed-disk 28 and projects under it, as shown in Fig. 2, so that it is adapted to engage a series of pins 37,'carried by and projecting downward from the seed-disk 28, one of said pins being provided for each of the The inner end of the pawl 30 is provided with fingers 38 39, forming a f'ork or socket adapted to receive the pins 37 as shown. The outer finger 38 is somewhat longer than the inner finger 39.

40 indicates a spring adjustably secured to the frame 4 and secured also to the arm 32. Said spring exerts a forward pull on the arm 32 and serves to draw the vpawl 30 forward after each operation. The pawl 30 is so arranged with reference to the seed-disk 28 that when it moves far enough to carry the seeddisk y28 around so as to bring the next hole 29 into position over the seed-tube the intermediate portion of said pawl will bear against the next pin 37, as shown in Iig.A 3. Inasmuch as the fingers 38 39 will at such time engage the next pinto the rear, as shown in Fig. 3, the finger 39 preventing outward movement of the pawl, said pawl, together with thepins 37 engaged by it, will lock the seed-disk valve and prevent it from moving beyond the proper point. It will thus be seen that an automatic lock is provided which prevents excessive movement ofthe seeddisk and insures the registration of the holes 29 with the seed-tube. As soon as the fork 14 is released from the knot on the checkrow wire the shaft 13 Will rock forward under the action of the spring 40, the arm 32 being carriedforward and carrying with it the pawl 30. The' swinging of the arm 32 about its pivot will automatically carry the pivot 31 of the pawl forward faster than the arm 36 and will consequently rock said pawl about its pivot 31, throwing its rear end inward and insuring the proper engagement of said pawl with the next pin 37. To prevent reverse rotation of the seed-disk 28, a detent 41 is provided, which engages the pins 37 successively, as shown in Fig. 2, said detent being normally held in operative position by a spring 42, as shown in Figs. 2 and 3.

Instead of arranging thepawl 30 so that the locking is effected by the engagement of the intermediate portion thereof with one ofv the pins 37 some other device maybe provided, so arranged as to engage the intermediate portion of the pawl when moved to the proper point-such, for example, as a fixed pin on the seedbox. I therefore do not wish to be limited to the specific arrangements shown except in so far they are specifically claimed.

That which I claim as my invention, and desire to secure by Letters Patent, is

1. In a seeding-machine, the combination of a seed-tube, a fertilizer-tube, a spring-controlled pivoted check-valve in said seed-tube, a pivoted check-valve in said fertilizer-tube, 'a link connecting said valves, and a reciprocating plunger adapted to engage one of said valves to operate the same and thereby simultaneously operate the other of said valves.
